Radio City, Ecuador (a joint association
between "El Universo", the biggest newspaper in Ecuador, and the BBC)
(April 21 2004) "Buscando la Luna" ("Seeking the moon") -
This is a rather strange interview since the radio station would not release
either their interviewer's questions, nor the lengthy Spanish translations
of Prof Leighton's responses, for publication on the web. These items have
therefore been edited out.

This is a discussion of
the bubble nets of humpback whales; of how dolphins might use sonar; and of
twin-twin transfusion syndrome and how bubbles might assist with this
medical condition.
